CREDIT CARD APPLICATION TURN AROUND TIME VERY SLOW

I am getting really discouraged by Nedbank and the lack of assistance. I app**** for a credit card on Monday 6th October, after a back and forth with requesting documents, I finally was given an offer. I logged into the app and it gave me an error to accept the offer. I then called the call center to which I was assist, received the contract and was told to sign and send back which I did immediately. My app still does not work and no word back as to what is happening since I sent the signed contract back to the consultant that assisted me. How long does it take to get feedback or to finalize an application?
